- Star count alone underwrote the round; sustained acceleration over 8 years
Grafana is the archetypal OSS dashboard tool. The repo's star count alone — over 55K at the time of the Series D — would have flagged it as a category leader to any sourcing system.
What made the Series D priceable at $6B was the *combination* of OSS leadership and enterprise-tier customer references. Grafana Cloud had been growing into a serious paid offering through 2021.
The $240M Series D in April 2022 capped a multi-year story. The lesson: very-high-star OSS dev tools almost always end up priced at unicorn-or-better multiples.

Frequently asked questions
Does raw star count still carry signal?
For developer tools with mature OSS funnels — yes. A repo above 50K stars in a sustainable category is a strong predictor of unicorn-tier outcomes.
